I bought a no-name aluminum housing from Parts Geek last fall (Sept/early Oct), and it's been working just fine with no leaks. It originally came up on WalMart.com when I was searching, but since it was coming from Parts Geek anyway, I went to them directly. Cost was $50 something. I did reuse my original sensors rather than the ones that came with it. There was no part #, brand, or any other marking on it. It's all polished, not like that Dorman part. Maybe I got lucky, but it fits well with no leaks.
